20CrMo ishidi lensimbi eligoqiwe elishisayo

amabha ensimbi ayindilinga asetshenziswa kakhulu ekwenzeni imishini, ukwenza i-autombile, ujantshi, imishini yezimayini, imishini ye-petoleum, imishini yezolimo kanye ne-civil archtectue efana nazo zonke izinhlobo zamashafu, izikulufu, izinduku zokuxhuma, amathuluzi ehadiwe, amagiya, izingxenye ezijwayelekile, izinsimbi zokubopha, izakhiwo. izingxenye zemishini yezimoto nezolimo, imikhono yangaphandle nengaphakathi, amarola namabhola okwenza amabhola.
I-GB 20CrMo steel iwuhlobo lwensimbi ye-Chinese alloy for engineering kanye nenhloso yesakhiwo sokusebenza, evame ukusetshenziswa ekucimeni noma ekushiseni noma ekungcwabeni nasekucimeni. I-20CrMo impahla inamandla okushisa aphezulu, ukuqina okuhle, akukho brittleness, i-cold strain plasticity, machinability enhle kanye nokushisela.

Izinhlelo zokusebenza

Insimbi ye-20CrMo ingxubevange isetshenziswa ekwenzeni imidiya engagqwali emishinini yamakhemikhali namapayipi anengcindezi ephezulu, izixhumi, izinjini zesitimu, ama-boiler blades kanye nama-forgings anezinga lokushisa elisebenzayo elingaphansi kwama-250 ° C, kanye nezingxenye ezibalulekile zokungcwaba ezifana namagiya namashafu emishinini ejwayelekile. . Ingasetshenziswa futhi esikhundleni sensimbi engu-1Cr13 ukwenza umfutho ophakathi nendawo, izinjini zesitimu ezinomfutho ophansi endaweni yokucindezela eshisa kakhulu izindwani ezisebenzayo.

Ukucaciswa Kokwelashwa Kokushisa

• Izinga lokushisa lokuqala lokucisha: 880 °C (I-ejenti yokucisha: amanzi, uwoyela)
• Ukushisa okushisa: 500 ° C (i-ejenti - amanzi, uwoyela)
